T0 at whom it may concern:

Be it known that 1, JOHN PATTERSON, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvem ents in Coin-ControlledElectrical Apparatuses, of which the following is a specification.

This invention relates to improvements in electrical apparatuses to beused for therapeutical purposes; and it consists in certainpeculiarities of the construction, novel arrangement, and operation ofthe various parts thereof, as will be hereinafter more fully set forthand specifically claimed.

The objects of my invention are, first, to provide an apparatus wherebyan electrical current may be passed through the body of the user and theforce of the current indicated, and, second, such an apparatus whichshall be operated only by the deposit of a coin of a certain size.

In order to enable others skilled in the art to which my inventionpertains to make and use the same, I will now proceed to describe it,referring to the accompanying drawings, in which- Figure 1 is aperspective View of my appatatus. Fig. 2 is an enlarged verticalsectional view taken on line 2 2 of Fig. 1, and Fig. 3 is a plan view ofthe mechanism with the batteries omitted.

Similar letters refer to like parts throughout the different views ofthe drawings.

A represents the box or casing in which the operating mechanism islocated and which has in its front end a glass at, through which theindicating-dial B may be seen, which dial may be provided withgraduating marks or characters of any desired kind and number. Locatedwithin the casing A is a metal frame C, on which the various parts ofthe operating mechanism are mounted. The top of the easing is providedwith a slot a, from which extends downwardly a chute a through which acoin of the desired size and denomination may be passed when it isdesired to operate the device. Directly below the lower end of the chutea is located the coin-holder B, which is substantially rectangular, asshown in Fig. 3 of the drawings, and is provided with a screw (Z to beused for regulating the size of the opening therein, so as to receive acoin of the requisite size and denomination. This holder is mounted on ashaft D, suitably journaled in the casing A, and has two contact-arms Dand D the purposes of which will be presently explained. On the outerend of the shaft D is fixed a crank D for turning the coin-holder soasto set the mechanism in operation and to release the coin. To the arm Dis secured one end of the spring E, whose other end is secured to ascrew or bind ing-post e in the side of the casing or box. Extendinghorizontally and rearwardly from the frame 0 are arms 0, o, and c andjournaled on the arms 0 and c isa shaft F, which is provided near one ofits ends with a gear 9 to engage the rack-bar h on the upper surface ofthe pull rod or bar H, which passes through asuitable opening in thefront of the casing and has an upturned end It, bymeans of which thesaid bar may be pulled forward by the finger of the user. This bar isretracted by means of a spring 77, secured at one of its ends to thecasing and at its other end to the bar or a screw thereon. Near theother end of the shaft F is located a bevelgear f, which meshes with asimilar gear f on the shaft F, which shaft is journaled at right anglesto the shaft F and passes through the dial-plate I3 and has on its outerend an indicating-hand I). Secured to the arm 0 of the frame 0 andlocated thereabove is a clock work-frame G, in which is journaled adriving-shaft G, to which is secured one end of a spring G whose otherend is secured to the frame G or otherwise. Fixed on the end of theshaft G adjacent to the shaft D is a piece or casting H, which hasalaterally and downwardly extending arm k against which the coin it willimpinge when the coin-holder is turned. This casting is provided withanother arm H to which is secured a fiat spring h which acts on thecontact-plate I, secured to and insulated from the casing G, whichcontact plate is provided with a deflection or bend 'i at its upper end.Mounted on the shaft G is a gear G which meshes with a pinion g on theshaft 9 which also carries a gear 9 meshing with a pinion g on the shaftg, on which is mounted a gear 9, which meshes with a {pinion on theshaft 9 on which is mounted another gear 5/,

which engages the escapementdetent g which is provided with an arm orlever g to control the same. Secured to the arm of the frame 0 is amagnet L and a circuitbrealrer L of the ordinary construction. Securedto the arm 0 is a doubly-wound induction-coil M, in which is movablylocated a core M, whose rear end is connected to the bar or rod H bymeans of a piece m, as is clearly shown in Fig. 2 of the drawings. Thewires n and n of the primary winding of the said coil are secured tosuitable binding-posts n on the piece N, by which the coil is supported,and the wires n and n of the secondary winding of said coil are securedto posts a on said supporting-piece. Leading from the post '11. to whichthe wire 12 is secured is a conductor 19, whose other end is connectedto the contact-plate I, and leading from the post n to which the wire isconnected is a conductor 19, which is connected at its other end to oneof the poles of the batteries P. Leading from the post a to which thewire 71, is connected is a conductor 0", whose other end is connected toone end of the metal handpiece R, and leading from the post it to whichthe Wire n is connected is a conductor 0, which is secured to the otherhandpiece R, which is also made of metal. Leading from the post 6, towhich the spring E is connected, is a conductor 4, which is connected atits other end to one of the poles of the batteries. Leading from thecontact-plate S, which is secured to the casing, is a conductor 8, whichis connected at its other end to the binding-post Z of thecircuit-breaker. The arm D is normally held in contact with the plate S;but as soon as the coin-holder D is turned said arm will be thrown outof contact with said plate and the circuit broken.

The operation of my apparatus is as follows: Coin is placed in the slotat and guided by the chute a to the holder D, when by turning thehandpiece D forward until it strikes the projection r on one of thehandpieces or grips the coin will strike the arm h of the piece H andturn it to almost a vertical position, in which operation the spring 72will be forced laterally by reason of the bend tin the contact-plate Iuntil it passes said contactplate, when the spring It will pass to theother side of said plate and contact therewith. In thus turning the armH the spring G of the clock mechanism will be tightened and the saidmechanism put in operation, and it is apparent that as soon as thespring h is brought in contact with the plate I the electric circuitwill be completed until the said spring is retracted to its normalposition by means of the spring E, which also acts as a conductor. Thecurrent will pass from the arm D through the arm D thence through theplate S, thence through the conductor 5 to the binding-post Z of thecircuit-breaker, thence through the frame 0 and the clockwork-frame G,and thence to the piece H and through the spring h to the plate I, withwhich it contacts.

By drawing the pull-rod H forward the hand I) will be turned so as toindicate on the dial-plate the force of the current, said hand beingoperated through the medium of the I'ZLGkrbflI' h, shafts F and F, andtheir gearlng.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

The combination with the case, of an inductioncoil and circuit breakertherein, grips or handpieces on the casing and adapted to be broughtinto circuit with such coil, a clock mechanism located within thecasing, a contact-plate secured near the clock mechanism, and having itsupper end deflected, a piece fixed on the driving-shaft of the clockmechanism, and carrying a spring to contact with said plate, acoin-holder journaled on the casing, a crank on the shaft of the holder,a guide leading from the exterior of the easing to the coin-holder, aspring-actuated rod movably connected with the core of the coil and anindicating-dial whose hand is operatively connected with said core,substantially as described.

JOHN PATTERSON.
